Abstract

The surface microtopography of Paramphistomum microbothrium and Cotylophoron cotylophorum was studied by Scanning Electron Microscopy (SEM) to investigate their morphological characteristics. The tegument posterior or to the anterior third in P. microbothrium has wrinkles or folds encircling the body but in C. cotylophorum the tegument in the same area is smooth. P. microbothrium has concentric aggregation of dome-shaped papillae located at it's anterior third, while the corresponding location inC. cotylophorum is with button-like papillae.
